alternative products:2 isoforms may be produced,catalytic activity:Release of mature proteins from their proproteins by cleavage of Arg-Xaa-Yaa-Arg-|-Zaa bonds, where Xaa can be any amino acid and Yaa is Arg or Lys.,domain:The propeptide domain acts as an intramolecular chaperone assisting the folding of the zymogen within the endoplasmic reticulum.,function:Likely to represent a widespread endoprotease activity within the constitutive and regulated secretory pathway. Capable of cleavage at the RX(K/R)R consensus motif.,similarity:Belongs to the peptidase S8 family.,similarity:Contains 1 homo B/P domain.,similarity:Contains 1 PLAC domain.,tissue specificity:Expressed in T-lymphocytes.,
[Isoform PC6A]: Secreted. Secreted through the regulated secretory pathway. .; [Isoform PC6B]: Endomembrane system; Single-pass type I membrane protein. Type I membrane protein localized to a paranuclear post-Golgi network compartment in communication with early endosomes. .
Expressed in T-lymphocytes.
